API / Js / Vector

You are currently looking at the v6.0 - v8.2 docs (Reason v3.6 syntax edition). You can find the latest API docs here.

(These docs cover all versions between v3 to v8 and are equivalent to the old BuckleScript docs before the rebrand)

Vector

Provide vector utilities.

t

RE
type t('a) = array('a);

filterInPlace

RE
let filterInPlace: ((. 'a) => bool, t('a)) => unit;

p : predicate a : array

empty

RE
let empty: t('a) => unit;

pushBack

RE
let pushBack: ('a, t('a)) => unit;

copy

RE
let copy: t('a) => t('a);

Create a shallow copy of a vector.

memByRef

RE
let memByRef: ('a, t('a)) => bool;

Find by JS (===) equality.

iter

RE
let iter: ((. 'a) => unit, t('a)) => unit;

iteri

RE
let iteri: ((. int, 'a) => unit, t('a)) => unit;

toList

RE
let toList: t('a) => list('a);

map

RE
let map: ((. 'a) => 'b, t('a)) => t('b);

mapi

RE
let mapi: ((. int, 'a) => 'b, t('a)) => t('b);

foldLeft

RE
let foldLeft: ((. 'a, 'b) => 'a, 'a, t('b)) => 'a;

foldRight

RE
let foldRight: ((. 'b, 'a) => 'a, t('b), 'a) => 'a;

length

RE
let length: t('a) => int;

Return the length (number of elements) of the given array.

get

RE
let get: (t('a), int) => 'a;

Vector.get(a, n) returns the element number n of vector a. The first element has number 0. The last element has number Vector.length(a) - 1. You can also write a[n] instead of Vector.get(a, n). Raise Invalid_argument "index out of bounds" if n is outside the range 0 to (Array.length(a) - 1).

set

RE
let set: (t('a), int, 'a) => unit;

Vector.set(a, n, x) modifies vector a in place, replacing element number n with x. Raise Invalid_argument "index out of bounds" if n is outside the range 0 to Array.length(a) - 1.

make

RE
let make: (int, 'a) => t('a);

Vector.make(n, x) returns a fresh vector of length n, initialized with x. All the elements of this new vector are initially physically equal to x (in the sense of the == predicate). Consequently, if x is mutable, it is shared among all elements of the array, and modifying x through one of the array entries will modify all other entries at the same time. Raise Invalid_argument if n < 0 or n > Sys.max_array_length. If the value of x is a floating-point number, then the maximum size is only Sys.max_array_length / 2.

init

RE
let init: (int, (. int) => 'a) => t('a);

Raises RangeError when n is negative. n : size

append

RE
let append: ('a, t('a)) => t('a);

append(x, a) returns a fresh vector with x appended to a.

unsafe_get

RE
let unsafe_get: (t('a), int) => 'a;

unsafe_set

RE
let unsafe_set: (t('a), int, 'a) => unit;
